Automatic quantitative packing machine with automatic feeding function

Abstract

The invention provides an automatic quantitative packing machine with an automatic feeding function and belongs to the technical field of packaging machinery. The automatic quantitative packing machine comprises a rack, a weighing mechanism, a filling discharge bag clamping mechanism and a storing cylinder, wherein a rack platform is arranged at the top of the rack; the weighting mechanism is arranged on one side of the rack platform facing upward; the filling discharge bag clamping mechanism is connected to one side of the rack platform facing downward; and the storing cylinder is arranged on the one side of the rack platform facing upward. The automatic quantitative packing machine with the automatic feeding function is characterized by further comprising a spiral material conveying mechanism, a power transmission mechanism and a spiral feeding mechanism, wherein the spiral material conveying mechanism is arranged in the storing cylinder, the power transmission mechanism is arranged on the one side of the rack platform facing upward, and the spiral feeding mechanism is arranged in the storing cylinder. The automatic quantitative packing machine has the advantages that the weighting mechanism is guaranteed to weight normally to enable the automatic quantitative packing machine to work constantly and normally, materials with poor mobility can be fed, and the weighing accuracy of the weighing mechanism is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of packaging machinery, and in particular relates to an automatic quantitative packaging machine with automatic feeding function. Background technique [0002] For fine chemical raw materials such as ultrafine powders, metal ore and non-metallic ore powders, pharmaceutical and chemical raw materials, dyes, pigments, calcium carbonate, kaolin, phenolic resins, and even food such as flour, food seasonings, etc. Or the packaging of granular materials is generally gradually transitioned from the past manual packaging mode to the current semi-automatic and fully automated mechanical packaging. The automatic quantitative packaging machine has the advantages of high packaging efficiency, accurate measurement, less manpower input, and helps to reduce the labor intensity of workers, so it is widely used by manufacturers who are not limited to the products mentioned above. [0003] In the Chinese patent literature, t...

Problems solved by technology

The weighing process of this scheme is cumbersome, and there are many action links, especially because the spring connected to the small door pull rod, the extension spring connected to the support rod and the spring connected to the slip bracket are used, and the spring and extension spring are prone to fatigue phenomenon, so the effect on the small door pull rod and slips will deteriorate over time, making it difficult to ensure the accuracy of measurement and the clamping effect on the packaging bag

In addition, the overall structure is relatively complicated; for another example, the announcement numbers proposed by the same applicant are respectively CN2778680Y and CN2778681Y, and the titles are respectively the weighing type automatic quantitative packaging machine and the hanging type automatic quantitative packaging machine. And supplementary materials, in order to reflect the accuracy of measurement, specifically, please refer to the 10th-21st line of the 4th page of the instruction manual of CN2778681Y

However, the correctness of the disposal measurement needs to be manually handled by the online operator, so it is more troublesome

[0007]However, the deficiency of the above-mentioned CN2538672Y, CN2778680Y and CN2778681Y on feeding is recommended by the invention patent publication number CN102417047A (automatic quantitative packaging machine with automatic feeding function) eliminated by the technical solution

[0008]However, CN102417047A is often difficult to meet the desired requirements when feeding materials with poor fluidity and / or high moisture content, that is to say, when encountering materials with poor fluidity , the feeding effect is less
